Diethyl acetylenedicarboxylate Chemical Properties,Uses,Production
Chemical Properties
Diethyl acetylenedicarboxylate is a clear light yellow liquid which has a disagreeable smell. It is a cheap and readily available material in industry. The triple bond is a critical and useful functional group, and it has extensive applications in organic synthesis. It can react with amines, aldehydes, ketones, etc. Therefore it can be used to form various heterocycles.
Synthesis of diethyl acetylenedicarboxylate
Uses
Diethyl acetylenedicarboxylate is used as a protein cross-linker. It is also used in the synthesis of 3,4,5-trisubstituted 2(5H)-furanone derivatives, highly functionalized thiazolidinone derivatives, novel cyclic peroxide glucosides and 4,11-dimesitylbisanthene, soluble bisanthene derivative, via Diels-Alder reaction.
General Description
Diethyl acetylenedicarboxylate is a protein cross-linker.
Purification Methods
Dissolve the ester in *C6H6, wash it with NaHCO3, H2O, dry over Na2SO4, filter, evaporate and distil it in a vacuum [IR: Walton & Hughes J Am Chem Soc 79 3985 1957, Truce & Kruse J Am Chem Soc 81 5372 1959]. [Beilstein 2 H 803.]
